resource/nav2_wfd': doesn't exist or not a regular file

[MAVProxyUser]

Any idea how to solve this?

$ colcon build --packages-select nav2_wfd Starting >>> nav2_wfd --- stderr: nav2_wfd
error: can't copy 'resource/nav2_wfd': doesn't exist or not a regular file

Failed <<< nav2_wfd [2.75s, exited with code 1]

Summary: 0 packages finished [3.41s] 1 package failed: nav2_wfd 1 package had stderr output: nav2_wfd

Sorry it's been awhile since I've looked at this. Just some guesses, did you pull the repo into your workspaces src directory? If so it's possible you need to change the folder name to nav2_wfd

That is exactly what I tried.

Where should the "resource" directory exist?

Just pushed a new commit. Looks like there's just an empty file in there but I've pushed it just in case. Can you pull the latest and try again?
